Class DelegatingTilesRequestProcessor

          org.springframework.web.struts.DelegatingTilesRequestProcessor

public class DelegatingTilesRequestProcessor
extends TilesRequestProcessor
extends TilesRequestProcessor

Subclass of Struts's TilesRequestProcessor that autowires Struts Actions defined in ContextLoaderPlugIn's WebApplicationContext (or, as a fallback, in the root WebApplicationContext).

Behaves like DelegatingRequestProcessor, but also provides the Tiles functionality of the original TilesRequestProcessor. As there's just a single central class to customize in Struts, we have to provide another subclass here, covering both the Tiles and the Spring delegation aspect.

The default implementation delegates to the DelegatingActionUtils class as fas as possible, to reuse as much code as possible despite the need to provide two RequestProcessor subclasses. If you need to subclass yet another RequestProcessor, take this class as a template, delegating to DelegatingActionUtils just like it.
